My nextcloud desktop Fedora 33.0.2 client syncs fine until I include an encrypted folder. In the Settings I see a red line for each file in the encrypted folder ending in could not be located.
There are no errors reported on the server (NC 33.0.2), only at the client. The App version on the server is End-to-End Encryption, Version 2.1.0, AGPL-licensed
The logfiles ~/.local/.share/Nextcloud contain no errors:

EDIT: I’ve setup a VM with Windows 11 and Nextcloud Desktop-Client-Version 33.0.2 (Windows läuft auf windows) and only synced the encrypted folder which is synced without a problem. It looks a specific problem with the Nextcloud version 33.0.2 AppImage (Nextcloud Desktop Client version 33.0.2 (Fedora running on xcb)
